The 3DS version looks better in my opinion. I was planning on getting the HD collection, but I think I'm going to get the 3DS version now. Also Kojima said that he might release MGS 2 on 3DS.
They touched up character models, but sacrificed other elements in order to do so. Basically, if you care more about how the people look you'll be happier, but if you enjoyed the environments before or were looking forward to nice looking jungles you might be really disappointed if you don't care about the 3D functionality.
